[R] Help transforming a dist

[Sarah Goslee]

I'm not at all sure what you mean with your matrix: is that supposed to
be three columns? What about:

> fakedata <- data.frame(X=runif(3), Y = runif(3))
> rownames(fakedata) <- c("A", "B", "C")
> dist(fakedata)
          A         B
B 0.8617733
C 0.3813032 0.5124284
> data.frame(t(combn(rownames(fakedata), 2)), dist=as.vector(dist(fakedata)))
  X1 X2      dist
1  A  B 0.8617733
2  A  C 0.3813032
3  B  C 0.5124284
